text: Using the relationships defined by this equation, the diffusion coefficient of the electroactive species can be determined.  Linear plots of i vs. ν provide evidence for a chemically reversible redox process vs the cases where redox causes major structural change in the analyte.  For species where the diffusion coefficient is known (or can be estimated), the slope of the plot of i vs. ν provides information into the stoichiometry of the redox process.
